Once there was the “video” tag, but content distributors decided it wasn’t enough. They wanted more—more power, more protection, more control—so encrypted media extensions were born, and digital rights management appeared in our browsers. Sebastian Golasch walks you through the technical details behind EMEs, CDMs, and DRM by reverse engineering and building a Netflix video player. You’ll learn how Sebastian came to understand the messy, monstrous world of DRMed videos on the web, how fragmented this ecosystem is, and who is in control of what. It’s a depressing but fun journey full of WTFs and technical and legal constraints.
